IRRIGATING APPARATUS.

A pplicationfiled April-'26, 19115; SerialNo; 935736; I

To all whom/it may concern:

Be itknown that I, JAMES M. LANGFORD, a citizen of the United States, residing at Mulberry, in the county of Polkand' State of Florida, have invented certain new and. useful Improvements inv Irrigating Apparatus; and I do: hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in irrigating apparatus, and consists more particularly in an improved apparatus of large dimensions for stationary and permanent installation, and which will be ar ranged to distribute water over a wide area.

It is an object of the present invention to provide a rotary reaction apparatus of improved construction and adapted more particularly for irrigating farm lands; such apparatus, broadly stated, consisting in a rotary head in communication with a source of water supply and having radiating'therefrom a plurality of perforated pipes for distributing the water, and which pipes are supported by connections from a mast erected in the rotary head and having a bearing cap fitted over its upper end and supported from guy wires.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a top plan view of an irrigating apparatus as constructed in accordance with the present invention; and

Fig. 2 is a fragmentary enlarged elevational view, with parts shown in section, of the same.

Referring now more particularly to the drawings, 1 designates a foundation of concrete or other suitable material laid at the proper location -in the field and having a central opening 2. A stationary pipe 3 projects up through the opening 2 in the foundation 1, and is in communication with a water supply.

On the foundation 1 is a base plate 4, se-. cured thereto by anchor bolts 5 and formed connections 23 for considerable depth in the with a centralopening 6 to agree'and register'with' the: opening 2: of the structure 1..

A turn table 7 is supported! to: rotate on thebase plate 4', there being complementary races formed. between said turn-table and base plate: to receive bal'l bearingsS. The turnrtable 7 is formed with; a central reduced opening 9 into which: projects theupper end of the stationary pipe 3'.

Bolts 10 connect a stuffing box 11 beneath and a threaded stub pipe 12 above the turntable 7, as plainly disclosed in" Fig. 2. A rotary hollow head 13: is adjusta-bly threaded on the stub pipe 12 and is provided with threaded branches 14 for receiving the threaded ends of the distributing pipes 15. These distributing pipes 15 are produced with perforations 16 in the rear walls thereof with reference to the direction of rotation, it being understood that the water issuing' therethrough. will by its reactionary cf f'ect rotate the apparatus substantially after the principle of the Barkers mill.

t its upper end the distributing head 13 is formed with a threaded socket 17 in which is secured a hollow mast 18. 'At its upper end the mast 18 is threaded to receive a cap 19 having an upwardly projecting journal 20 rotatably fitted within a bearing block 21. Between the bearing block 21 and cap 20 are races wherein operate ball bearings 22 for reducing the friction at this point.

Between the cap 19 and distributing pipes 15 are strung wires or other rigid or flexible supporting such pipes, as, in practice, the distributing pipes will extend to great length in order to include a wide area of the field. These distributing pipes 15, as shown in Fig. l, are also preferably connected to each other through wires orother flexible 0r rigid connections 24 for preventing bending, distortion, or relative displacement of the same.

The bearing block 21 is maintainedin position by guy wires 25 running to stakes or posts 26 driven in the ground just beyond theends of the distributing pipes 15, and

from these posts 26 the guy'wires 25 or other men 27 sunk to a ground.

When water is permitted to issue up through the stationary pipe 3 in the foundation 1,' it will pass upwardly therethrough into the distributing head 13 through the wires are carried to dead stub pipe 12, and will thence flow into thellO radius of fifty feet has distributing pipes 15 and will issue out through the perforations 16 in fine jets, its reactionary effect being to rotate the apparatus about the foundation 1 and the base plate 4 on the turn-table 7. Any undue friction between the stationary and rotating parts will be taken up by the ball bearings 8 between the turn-table and base plate and the ball bearings 22 between the mast cap 19 and bearing block 21.

I have found in practice that the device can be manufactured at very small cost, and an apparatus having an effective working been put into successful operation. The distributing pipes 15 are to be supported at an elevation which would admit of plowing beneath them, it being understo d that the whole system is to be permanently located.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.

I claim:

1. In an irrigating apparatus, the combination of a foundation, a base plate on said foundation, a stationary pipe projecting through said foundation and in communication with a water supply, a turn-table supported to revolve on said base plate, a stuff- Gopies of this patent may said turn-table and embracing said stationary pipe connected above said turn-table, a dis head adjustably connected to said tributing pipes radiating stub pipe, and distributing from said distributing head, substantially as described.

2. in an irrigating apparatus, the combination of a foundation, a base plate on said foundation, a stationary pipe projecting through said foundation and being in communication with a source of water supply, a turn-table supported to rotate on said base plate, ball bearings arranged between said turn-table and base plate, a stutiing box secured to said turn-table and embracing said stationary pipe, a threaded stub pipe on the upper end of said turn-table, a rotary head adjustably threaded on said stub pipe and in communication therethrough with the water supply from said stationary pipe, perforated distributing pipes extending from said rotary head, a mast erected on said rotary head, tween said mast and distributing pipes, a journal on the upper end of said mast, a bearing block fitting said journal, posts, and gu wires connected between said bearing block and posts, substantially as described.

In testimony whereof, I afiiX my signature.
